If your furnace pilot light is out, there are several signs you can look for to confirm the issue. The first sign is if your furnace isn’t producing heat. If you’ve noticed that the furnace isn’t running or isn’t providing heat as it usually does, it’s likely that the pilot light is out.
You can also check the bottom of your furnace unit to see if the pilot light has gone out. You’ll need to turn off the power to the furnace to safely open the exterior and look inside at the pilot light.
If it’s not lit, then the pilot light is out and needs to be reignited. Another indicator of a pilot light being out is if you can smell gas coming from the area around the furnace. If you smell gas, it’s important to leave the area immediately, call the gas company, and open windows and doors to ventilate the house.
Then you can call a professional to address the pilot light issue.

What happens if pilot light goes out on furnace?
If the pilot light on a furnace goes out it can be a sign of an issue with the appliance. It is important to call a professional to inspect the furnace and perform any necessary service or repairs. The most common cause of the pilot light going out is a blocked burner orifice, which is the small hole that releases gas from the furnace into the combustion chamber.
If the orifice is blocked, the flame will be extinguished, resulting in the pilot light going out. Additionally, a dirty or weak thermocouple or a faulty thermopile can also be the cause of a pilot light going out.
A thermopile helps to detect an open valve and a thermocouple helps to sense the flame and keep it burning. A professional technician can use special gauges and tools to diagnose the issue and determine how to proceed with any necessary repairs.
Once the issue is identified and the repair is performed, the furnace should be inspected to make sure it functions properly and no other issues are present.
Will furnace kick on without pilot light?
No, a furnace will not typically kick on without a pilot light. In order for a furnace to ignite and turn on, the pilot light needs to be lit. This is because the pilot light provides a continuous flame which acts as the source of ignition for the combustion inputs that the furnace needs to turn on and run.
The furnace is designed to utilize the pilot light as the source of ignition, meaning that it will not kick on until this has been lit. To ensure that the pilot light is staying lit and the furnace is able to turn on, it is important to check the pilot light and make sure that it is lit every once in a while.
How do I relight the pilot on my furnace?
Relighting the pilot on your furnace is a fairly straightforward task that can be completed in just a few steps.
First, make sure there is no gas flowing through the furnace by turning off the gas valve. Then, locate the small pilot flame located near the burner of the furnace. If the pilot light is out, you will need to reset it.
To reset the pilot light, press the reset button. This will activate the electronic igniter and heat the thermocouple. When the thermocouple detects a flame, it will turn on the gas valve.
Next, locate the knob near the pilot flame. This knob controls the gas flow and should be turned to the “On” position. Depress the knob and hold it for about a minute, and then release it. This will allow gas to flow, and if all is properly connected, the pilot flame should ignite.
If the flame does not ignite after attempting this, you may need to adjust the knob slightly to increase the flow of gas to the pilot flame. After the desired flame is achieved, turn the knob to the “Off” position, and the pilot should stay lit.
Once the pilot is lit, it is important to monitor it periodically to ensure it remains lit. If you notice the flame going out, simply repeat the above steps and monitor the flame to ensure it stays lit.
Is it easy to relight a pilot light?
Relighting a pilot light is not very difficult and can typically be done with minimal effort. First, you will need to shut off the gas supply to the pilot light before attempting to relight it. Once the gas supply is off, you will need the right materials to relight the pilot light.
You should have an adjustable wrench, lighting device (such as a match or barbecue lighter), and a cloth to cover the valve. Begin by taking the cover off the pilot light, removing the burning material, and examining the burner.
Use the adjustable wrench to loosen the gas valve and then open the gas valve a few turns. The gas valve must be opened very slowly and it should be no more than one eighth of a turn in order for the pilot light to stay lit.
Next, use a match or barbecue lighter to light the pilot light and not an open flame. When the pilot light is lit, slowly close the valve and replace the covering on the pilot light. Ensure that the area is well ventilated to ensure that the gas dissipates freely.
After the pilot light is lit, check the flame color to make sure that it’s blue. If it’s yellow, reduce the gas flow. Relighting a pilot light isn’t overly complicated, but you should ensure that you work in a well-ventilated area and take all the necessary safety precautions when attempting to relight any gas-operated pilot light.
How long does it take to relight a pilot?
Relighting a pilot light may take anywhere from a few minutes to an hour, depending on the type of appliance, the specific model, and the amount of experience of the individual relighting the pilot light.
Before attempting to relight the pilot light, make sure to shut off the gas to the appliance, wait at least 10 minutes (to ensure all gas has been cleared from the space), and then if you feel comfortable relighting the appliance, follow the manufacturer’s instructions carefully.
Once you are sure the gas is off, the pilot light can be relit with a special tool such as a long-handled lighter or a match. Make sure to hold the flame close to the pilot light, but not too close so it does not ignite the gas.
After a few minutes, if the flame remains lit, you can turn the gas back on and allow the flame to adjust before turning the appliance back on.
Overall, the time it takes to relight a pilot light will depend on the individual and the type of appliance, but it could take anywhere from a few minutes to an hour.
Can you get carbon monoxide poisoning from a pilot light?
Yes, it is possible to get carbon monoxide poisoning from a pilot light. A pilot light is a small gas flame that is kept burning continually. They are commonly used on gas furnaces, water heaters, stoves, and other small gas appliances.
If the pilot light isn’t burning correctly, it can cause the appliance to emit carbon monoxide gas into the air. In high enough concentrations, carbon monoxide can be fatal. Removing yourself and any other occupants from the space, and having the appliance inspected and repaired by a professional is the best course of action when a pilot light is suspected of producing carbon monoxide.
Can a pilot light out cause carbon monoxide?
Yes, a pilot light out can cause carbon monoxide. This is because when a pilot light goes out, the gas may not be burning completely, which can lead to a buildup of carbon monoxide in the air. Carbon monoxide is an odorless, colorless gas that can be deadly when breathed in over long periods of time.
Although the amount of carbon monoxide produced from a pilot light out is usually fairly small, it can still be dangerous and present a health risk to those living in the residence. Additionally, a continuous buildup of carbon monoxide can cause serious health problems, including unconsciousness, confusion, and even death.
Therefore, if the pilot light goes out, it is very important to get it fixed as quickly as possible by a qualified service technician.
How do you relight an automatic pilot light?
Relighting an automatic pilot light depends on the type of gas furnace. Generally, they all follow a similar set of instructions. First, make sure the gas line is shut off and ventilate the room by opening a window slightly.
Secondly, use a match or lighter to turn the valve to pilot and press the reset button. Hold the pilot light button for about 10 to 30 seconds to allow the flame to ignite. Finally, release the pilot button and turn the valve from “pilot” to “on.
” This will result in the heat activating, igniting the air through the vents in the house. If your gas stove does not light, then it is likely a problem with the gas supply or the pilot light itself.
Consider calling a qualified technician to address the issue.
Where is the pilot light located on a gas furnace?
The location of the pilot light on a gas furnace varies depending on the furnace’s make and model. Generally, it is located inside the furnace, with access to it from either the front or the top of the unit.
The pilot light is a small flame that burns constantly, providing a source of ignition for the main flame for the furnace. It is protected by a small, metal door. To access the pilot light, you may have to open the access door on the furnace, and then use a flashlight to locate the pilot flame.
You may need to remove the control knobs and screws on the control box to open the access door. Once the pilot light is accessible, you can light it with matches, a long lighter, or a special torch designed specifically to light pilot lights.
Will gas shut off if pilot light goes out?
Yes, if the pilot light goes out, the gas will shut off. This is a safety measure to prevent gas from flowing into the home when there is no source of ignition. Without the source of ignition, the gas can build up, creating the risk of an explosion.
When the pilot light goes out, typically the thermocouple or thermopile will notice and shut off the gas line.
Should I worry if the pilot light goes out?
It depends on the situation. Generally, if the pilot light in your furnace, hot water heater, or stove goes out, you should not worry. These pilot lights should automatically re-light themselves. However, it is important to be aware of the safety precautions to observe when the pilot light goes out.
You should ensure that the room is well ventilated and read the owner’s manual of the appliance to ensure that the pilot light is re-lit in accordance with the manufacturer’s instructions. If you are unable to relight it on your own or if it continues to go out, you should contact a licensed technician to inspect the appliance and make necessary repairs.
Why did my pilot light randomly go out?
If the flame on the pilot is too small, the system lacks enough air to provide a steady flame and will eventually go out. A clogged burner orifice can also cause an erratic flame and will eventually lead to the pilot light going out.
Finally, a faulty thermocouple may cause the pilot light to go out suddenly, as this device is the safety measure that turns off the gas supply if the pilot light goes out. To fix your pilot light and prevent it from going out again, you should start by checking the thermocouple to make sure it’s functioning correctly.
You should also check the burner orifice for clogs or debris and clean or replace it as necessary, and you can adjust the flame size if it is too small. If the issue persists, you may need to have a professional technician come in and inspect your system for any other issues.
Do all furnaces have a pilot light?
No, not all furnaces have a pilot light. Furnaces that are powered by electricity do not have a pilot light; instead, they rely on an electric igniter to light the burners. Meanwhile, furnaces powered by gas or oil may have a pilot light or an electric ignition system.
The type of fuel and the design of the unit will determine whether the furnace has a pilot light.
Pilot lights are small flames that burn constantly to help ignite the gas burner whenever the furnace turns on. When the thermostat calls for heat, the burner is ignited by the pilot light and then the fan turns on to distribute warm air throughout the home.
Pilot lights are common in older furnaces, however newer furnace models are more likely to have an electric igniter for the burners.
The main benefit of electric ignition systems is that they do not require a constant flame that uses fuel and increases the risk of a fire. It is important to note that a lit pilot light should always be checked by a professional before the furnace is used.
If you’re unsure if your furnace has a pilot light, contact a heating and air conditioning technician to inspect it.
Can I relight the pilot light by myself?
Yes, you can relight the pilot light yourself as long as you feel comfortable and knowledgeable about working with gas. In general, the process involves turning the gas valve below the furnace off, waiting several minutes for the natural gas to clear out of the lines, locating the pilot light, pushing the ignition control knob to the pilot light setting, and pushing the knob down to start the flow of gas.
After the pilot light is going, you must then hold the control knob down for about 60 seconds in order for the pilot light to warm the thermocouple enough for the main unit to ignite. Finally, you must release the knob and turn the gas back up so the furnace can work normally.
If the pilot won’t light after multiple attempts or the furnace doesn’t ignite, you should call a professional HVAC technician to correct the issue.
